Process for production of high quality gasoline with low aromatic content |
| abstract |
This patent presents a two-stage process for production of high-octane gasoline from a hydrocarbon stream comprising C 4 -C 12 hydrocarbon mixtures of paraffins, optionally including cycloalkanes, aromatics and olefins. During the first step linear molecules are activated and converted predominantly to mono-branched isomers. Present cyclic molecules and olefins are hydrogenated, but conversion must be sufficiently low to avoid ring opening. Only such (low) amount of multi-branched isomers is formed in the first reaction zone that extent of cracking is still acceptable. Concentration of multi-branched isomers is consecutively increased in the second step. Reaction of mono-branched isomers requires lower activation energy than cracking and isomerisation of linear molecules. Monomethyl-paraffins readily react to their multi-branched counterparts with a high selectivity under mild reaction conditions with catalysts having a Hammet acidity value lower than −10 at temperature of maximum 100° C. and at least 50° C. lower than in the first step. These are the conditions effectively isomerising hydrocarbon molecules containing tertiary carbon, while other feed components are little effected. The combination of both steps utilising different catalysts and conditions is essential to achieve a high selectivity. Both reaction steps can be combined with separation of low octane number paraffin molecules by a suitable separation process. |
